macOS No setup beyond a folder

Bookkeeping that runs itself.

Select a folder, paste your OpenAI token once, and Billly does the rest. It watches for new PDFs, extracts values via OCR + AI, and keeps revenue and profit up to date.

App is free. OpenAI usage is billed by OpenAI (roughly 50 invoices ~ 1 EUR).
